His beloved daughter was poisoned, and he lost his composure.

"Why... aren't they chasing us anymore?" Su Qinghan asked, panting, her face pale and filled with confusion.

"These Bone-Corroding Demon Worms have low intelligence; their actions are purely instinctive." Lin Yuan stared at the dark depths ahead, which exuded high temperatures.

"Their sudden stop can only mean one thing... deep within this cave, there's something that makes them extremely fearful."

"Never mind that for now, let's go in and see!" Yue Qingyao made a decisive move, no longer bothered by Lin Yuan's keen perception. Her figure flickered, and she was the first to fly towards the unknown area below.

Lin Yuan followed closely behind.

A moment later, their view suddenly opened up.

An incredibly vast underground cavern appeared before the three of them.

The cavern's dome hung high, with thick stalactites dangling down, their tips shimmering with a crystalline luster.

At the very center of the cavern, there was a milky-white pool, ten zhang in circumference.

The water in the pool churned, emitting misty hot steam, like a pot of boiling jade liquid.

And in the center of the pool, a half-human-tall, strange lotus plant grew quietly.

The entire lotus plant was fiery red, its leaves as warm and smooth as jade, and its petals tightly closed. Yet, a vast and powerful life force emanated from it, forming an invisible force field filled with pure masculine power.

The scorching heat that made the entire cave unbearable was emanating from this very lotus plant.

Su Qinghan's breathing hitched slightly.

In her beautiful phoenix eyes, the reflection of the crimson lotus plant was clearly visible, and an uncontrollable look of joy emerged from the depths of her eyes.

She instinctively moved her body, about to glide towards the pool.

However, Yue Qingyao suddenly reached out and pressed her hand on Su Qinghan's shoulder.

"Why are you so reckless? This place is too quiet; don't you notice something is off?"

As she spoke, Yue Qingyao's phoenix eyes did not linger on the lotus plant but instead vigilantly scanned everything within the cave.

It was too quiet here; besides the churning sound of the pool, there was not a single other noise.

Even the breathing and heartbeats of the three of them were exceptionally clear.

Lin Yuan's gaze was solemn.

Here, a thousand zhang deep underground, the air was free of poisonous miasma, Spiritual Qi was abundant, and Divine Sense was not suppressed.

With a thought, his Divine Sense spread out like a tide, sweeping over the high-hanging dome, scanning the rugged rock walls, and probing into every dark crevice.

A moment later, his brow furrowed almost imperceptibly.

His eyes were full of doubt; this place was actually a dead zone.

Aside from the three of them and the incredibly vibrant yang returning lotus, there was no other living creature.

Not even a flying insect or a ground maggot existed.

Yue Qingyao had clearly come to the same conclusion; though she had doubts in her eyes, she did not detect any danger.

"Qinghan, go and collect that yang returning lotus."

"Lin Yuan, prepare for Alchemy."

Lin Yuan nodded, his figure flickering as he landed on a relatively flat stone platform at the edge of the cave, preparing for the upcoming Alchemy.

Su Qinghan's figure floated lightly, gliding over the misty pool water, hovering directly above the yang returning lotus.

Her slender jade hand reached out towards the tightly closed crimson lotus petals.

Just as her fingertips were about to touch the petals, an unexpected change occurred!

The yang returning lotus actually came to life!

The lotus body trembled slightly, shifting to the side at an incredible angle, perfectly dodging her attempt to pluck it.

Its movements were full of spiritual sentience.

The next moment, the milky-white pool water below, which had only been bubbling, suddenly exploded!

A streak of snowy-white afterimage shot out from beneath the water!

It was a small snake, its entire body appearing to be carved from white jade.

It was no thicker than a thumb, yet it was extremely fast, transforming into a white line that tore through the air, flashing past along the stem of the yang returning lotus!

Puff!

Su Qinghan felt a chill on her wrist, followed by a sharp, piercing pain, as if an ice needle had stabbed into her bone marrow.

All of this happened in but a moment.

Su Qinghan cried out in alarm, instinctively shaking her arm.

The small white snake was flung away by her, hitting the distant stone wall with a crisp sound like metal striking metal.

But on Su Qinghan's wrist, a tiny tooth mark had already appeared.

The skin around the tooth mark was rapidly turning bruised at a terrifying speed.

Immediately after, an invisible ink quickly spread beneath the skin of her fair arm.

Purple-black spots, the size of copper coins, appeared out of nowhere and rapidly spread along her Meridians towards her shoulder!

"Oh no!"

Yue Qingyao's usually calm face was replaced by shock for the first time.

"It's a Frost-Bone Qiú! A Peak Fourth-Rank Yao Beast!"

Before her words finished, her figure had already appeared beside Su Qinghan, her fingers like lightning, swiftly tapping several vital acupoints around Su Qinghan's body, attempting to block the spread of the toxins.

But even with her Meridians sealed, the purple-black spots only slowed their spread slightly, still climbing upwards.

"This is an antidote Medicinal Pill, take it first!"

Yue Qingyao flipped her wrist, and a fragrant, snowy-white Medicinal Pill was sent into Su Qinghan's mouth.

The Medicinal Pill melted upon entry, transforming into a cool medicinal power that dispersed.

The spread of the purple-black spots slowed down even further.

But it still didn't stop, nor did it show any signs of receding.

On the other side, Lin Yuan's brows furrowed slightly. He had previously killed two Cultivators from the Five Poisons Sect and obtained a book called the Myriad Poisons Compendium.

It contained a record of this Frost-Bone Qiú.

The Frost-Bone Qiú, an ancient exotic species. Its bones are like frost, its body like jade, born in places of extreme yang, yet bearing the most yin of poisons. This poison does not harm flesh and blood, but specifically invades the Divine Soul and Dao foundation, and is extremely skilled at concealment. In the ranking of the Myriad Poisons Spectrum, this poison firmly holds a place within the top hundred!

There are tens of millions of poisonous creatures in the Cultivation world; to be ranked among the top hundred is synonymous with instant death upon contact!

Moreover, the most terrifying thing about the Frost-Bone Qiú is not its poison, but its formidable Physical Body, comparable to a Magic Treasure. Killing it is extremely difficult.

"Hiss—"

A sharp hiss echoed from the corner.

The small white snake that had been flung away slowly coiled its body. In an instant, Spiritual Light burst forth!

Its thumb-thick body rapidly expanded amidst a bone-cracking sound that made one's teeth ache.

Tiny, rice-grain-sized scales instantly transformed into palm-sized, jade-white armor, shimmering with a chilling cold light.

In just two or three breaths, a ferocious giant python, as thick as a water bucket and over ten zhang long, was coiled within the cave!

Its head was no longer snake-shaped but subtly showed a tendency to evolve into a Dragon head. Two prominent bone protrusions bulged on its forehead, and a pair of ice-blue vertical pupils, devoid of any emotion, locked onto the three of them.

A Peak Fourth-Rank Yao Beast! The fierce pressure it exuded was already comparable to a Late Foundation Establishment Stage Cultivator!

"Mother... I... I'm so cold..."

Su Qinghan's voice had begun to tremble, her lips drained of color, turning pale blue.

She could clearly feel a cold Death Qi rapidly eroding her heart and Purple Mansion through her arm, as if even her Soul was about to freeze.

At most... no more than a quarter of an hour.

Once the poison reached her heart, she would surely die!

"Don't be afraid, Mother is here!"

For the first time, a flicker of panic appeared in Yue Qingyao's eyes, and even her usually rock-steady hands trembled almost imperceptibly.

Her Cultivation was unrivaled among her peers in the Eastern Domain, but detoxification was not her forte.

Watching her daughter's life force rapidly drain away before her, even with her stable state of mind, she completely lost her composure at this moment.

"You go hold off that Frost-Bone Qiú, I'll give it a try!" Lin Yuan's voice sounded from behind them.

"You have a way?"

Yue Qingyao suddenly turned her head, her eyes bursting with intense surprise.
